This research is intended to reveal the correlations between diabetes and dietary and other related factors. We were studied for 257 diabetics, in t도 9 general hospitals, located at Seoul, From August 109 to September 3, 1986. The result of this study can be follow ; 1) Distribution of the subjects according to their general characteristics ; The sex ration of the subjects is 1.06 ; 1.00 (male ; female), and the average age is 54.7 $\pm$10.9 years. Among the subjects 28.8% have a family history of diabetes ; the closer the genetic relationship, the more hereditory factors play a part. 2) Distribution of the scores according to their socioeconomic status ; As the socioeconomic status goes p, the intake of calories and fiber increases ; however, the frequency of eating out and the degree of physical activity decrease. 3) Relationship between obesity prevalence and each variable ; Among the subjects 27.2% are obese, and 60.3% have been obese in the past. Even though there is no significant relationship between the food habit and obesity, the number of people who are obese shows a significant increase as the socioeconomic status improves. 4) The effect of sex on each variable ; The intake of calories, sugar, alcohol and coffee is higher in male subjects, as is the frequency of eating out. In regular exercise and physical activity, there are significant differences between male and female subjects.

In an attempt to analyze the characteristics of domestic pathogenic strains of S. pneumoniae, the basic epidemiological charactristics of pathogenic strains such as their serotypes and frequency of penicillin resistance, and pattern of chromosomal DNA from PFGE(pulsed-field gel electrophoresis) were observed. For this study,56 strains of S. pneumoniae isolated from inpatients and outpatients in the four domestic university hospitals were collected from January to December in 1998. Among those strains, a total of 56 pathogenic strains from blood(39 isolates), cerebrospinal fluid(8 isolates) and other specimen(9 isolates) were selected and isolated. The penicillin resistance frequency of those 56 strains was identified with disk diffusion method with 66.1％. From the invasive strains, predominant serotypes were isolated in the order of 19F(12.5％), 23F(10.7%), 14(10.7%) and 9V(10.7％), totalling 45 percent. This experiment also used PFGE patterns to compare the correlations among genetic subtypes in several serotypes. The DNA fragments digested with Sma I and Apa I were resolved by PFGE. The PFGE patterns digested with Sma I were better than Apa I for analysis. In the DNA fragments digested with Sma 1, PFGE analysis of 56 S. pneumoniae isolates showed 25 different patterns. As a result, serotype was on the whole correlated to PFGE pattern on the ground that each different PFGE pattern by serotype was observed. This study can be utilized not only fur the study of incidence trend of domestic pneumococcal diseases but also as a useful basic data for the development of identification tool and treatment.

Burns due to epileptic seizures are commonly deep and usually require operative treatment. The purpose of this study is to identify the characteristics of burned epileptic patients that could lead to the development of preventive programs to reduce the incidence of burn injuries. We analyzed epidemiological data for 34 patients acutely burned due to epileptic seizure admitted retrospectively. There were 15 male and 19 female subjects. The age distribution was from 6 years to 70 years with the mean age of 42.7 years. Seizures usually occurred while carrying out daily domestic chores. Scalding burns were the most common(38.2%) and most burns were above deep second degree(94.1%). The most common seizure type was generalized tonic-clonic, followed by absence and complex partial. The seizure mostly occurred in the morning because the therapeutic blood level of antiepileptic drugs was decreased extremely at that time by stopping drug arbitrarily or taking inadequately. So more frequent follow-ups at the neurology outpatient clinics for epileptics should be strictly reinforced to maintain the adequate therapeutic blood levels of antiepileptic drugs and fire protective implements should be prepared in the house.

Classical swine fever (CSF) was confirmed in 19 herds in Jeunbuk provence (Iksan, Gimje, Wanju, Buan, and Jangsu) in Korea between March and May, 2003 and 10,263 pigs were slaughtered. Pigs contacted with CSF virus in primary outbreak farm show fever, reduced appetite, arched back and chill in company with sever respirative sign and then most infected farms also were observed to fever, reduced appetite, sudden death, and leukopenia (101 pigs). In order to detecting infectious pig with CSF virus, A total of 555 pigs were inspected in 65 herds and blood samples were collected and serological test (ELISA), antigen ELISA, and reverse transcription-polymerase chain reaction (RT-PCR) had been done. Positive rate were $74\%$ (410 pigs) in antibody ELISA, $2\%$ (11 pigs) in antigen ELISA and $33\%$ (182 pigs) in RT-PCR, respectively. As shown that the RT-PCR was useful than the ELISA for determining CSF virus in blood, meat, and other organs.

Purpose: This study was done to examine the threshold value of estimated height loss at which the risk of osteoporosis increases and to verify its discriminative ability in the detection of osteoporosis. Methods: It was conducted based on epidemiological descriptive methods on 732 Korean women at a public healthcare center in Seoul between July and November 2010. ANOVA, Pearson correlation, logistic regression analysis and receiver operating characteristics (ROC) curve were used for data analysis. Results: There was an age-related correlation between bone mineral density (lumbar spine: F=37.88, p<.001; femur: F=54.27, p<.001) and estimated height loss (F=27.68, p<.001). Estimated height loss increased significantly with decreasing bone mineral density (lumbar spine: r=-.23, p<.001; femur: r=-.34, p<.001). The odds ratio for the point at which the estimated height loss affects the occurrence of osteoporosis was found to increase at a cut-off value of 2 cm and the area under ROC curve was .71 and .82 in lumbar spine and femur, respectively. Conclusion: The optimal cut-off value of the estimated height loss for detection of osteoporosis was 2 cm. Height loss is therefore a useful indicator for the self-assessment and prognosis of osteoporosis.

Objectives: The epidemiological characteristics of breast cancer incidence by age group in Korean women are unique. This systematic review aimed to investigate the association between hormone replacement therapy (HRT) and breast cancer risk in Korean women. Methods: We searched electronic databases such as KoreaMed, KMbase, KISS, and RISS4U as well as PubMed for publications on Korean breast cancer patients. We also conducted manual searching based on references and citations in potential papers. All of the analytically epidemiologic studies that obtained individual data on HRT exposure and breast cancer occurrence in Korean women were selected. We restricted the inclusion of case-control studies to those that included age-matched controls. Estimates of summary odds ratio (SOR) with 95% confidence intervals (CIs) were calculated using random effect models. Results: One cohort and five case-control studies were finally selected. Based on the heterogeneity that existed among the six studies (I-squared=70.2%), a random effect model was applied. The summary effect size of HRT history from the six articles indicated no statistical significance in breast cancer risk (SOR, 0.983; 95% CI, 0.620 to 1.556). Conclusions: These facts support no significant effect of HRT history in the risk of breast cancer in Korean women. It is necessary to conduct a pooled analysis.

Newcastle disease virus (NDV) is the causative agent of a highly contagious and devastating Newcastle disease of poultry. A NDV (isolate DK1/07) was isolated from apparently healthy wild spot-billed ducks (Anas poecilorhyncha) captured at upper branch of the SapGyo Creek in Chungbuk province, Korea during early 2007. The DK1/07 isolate of minimum chicken embryo lethal dose killed all SPF chicken embryos within 60 h. The cleavage site of the F protein possessed the amino acid sequence $^{112}R-R-Q-K-R-F^{117}$, which is a motif characteristic of virulent NDV strains. The F protein-based phylogenetic analysis revealed that the DK1/07 duck isolate was included in the cluster of genotype VIId and most closely related to recent NDV isolates obtained from chicken farms in Korea. Epidemiological importance of virulent NDV from wild duck is discussed.

Purpose: Methicillin Resistant Staphylococcus aureus (MRSA) has become a major clinical problem and one of the major nosocomial pathogen worldwide. The aim of the study was to investigate the epidemiological characteristics of genotypes of MRSA isolated in the A-hospital ICU. Methods: In the period between December 2007 and May 2008, MRSA was isolated from ICU patients and its surrounding environment. Polymerase Chain Reaction (PCR) was conducted for the detection of MRSA gene. The incidence of MRSA in the clinical isolates of Staphylococcus aureus was examined by using a multiplex PCR. The spa gene of Staphylococcus aureus encodes protein A and is used for typing of MRSA. We used sequence typing of the spa gene repeat region to study the epidemiology of MRSA at a hospital. Results: Two different genotypes of MRSA were identified with 90 isolated from the patients and its surrounding environments in the ICU. Conclusion: This study may contribute to the development of effective strategies for preventing nosocomial infections. Genotyping may have more general application for the study of MRSA epidemic outbreak in hospital and community infection.

Russian rates for melanoma incidence and mortality are relatively low as compared to some other white populations but the tumor is of increasing importance. In this paper, data are based on a retrospective descriptive analysis of melanoma epidemiology and clinicopathological characteristics in Krasnoyarsk Territory belonging to the Siberian Federal District of the Russian Federation. The age-adjusted incidence and mortality rates for the period 1996-2009 were determined with subsequent retrospective analysis of clinicopathological data of 103 primary melanoma cases. Our results showed that incidence and mortality rates in the region under consideration match the Russian national trends and correspond to epidemiological data of the countries of Eastern Europe. Stratification of melanoma cases by age, sex, clinicopathological state and localization revealed a prevalence of lesions on the trunk and lower extremities. Most melanomas diagnosed were of superficial spreading type and the third Clark's level of tumor invasion and stage II according to AJCC. In spite of comparatively low rates of incidence and mortality the trend to increase of melanoma cases in the region under consideration obviously calls for more attention and further investigation.
